PAPER-FOLDING MACHINE.

SPECIFICATION forming part of Letters Patent No. 461,422, dated October20, 1891.

Application filed March 21, 1891.

To all w/tom it may concern.-

Be it known that I, TALBOT-O. DEXTER, a citizen of the United States ofAmerica, residing at Fulton, Oswego county, State of New York, haveinvented a new and useful Improvement in Paper-Folding Machines, ofwhich the following is a specification.

The object of my invention is to facilitate the adjustment ofsheet-carrying mechanism as required to connect. and disconnect apaper-folding machine with a printing-press. Heretofore rigid andjointed boards and frames have been used for the purpose and rollers andtapes connected therewith in such a manner that they could be jointlylaid on top of the folding-machinewhen not in use.

My invention consists in the construction and combination of bracketswith the frame of a folding-machine to support rollers and tapes andalso to support the lower end of a skeleton'bridge that is adapted to beadj ustably and detachably suspended from the table of a printing-press,and also in the construction and combination of brackets adapted to beconnected with the top portion of the bridge to support rollers andframes in such a manner that the brackets at the topof the bridge can bedetached therefrom and the rollers and tapes on the brackets jointlyhandled and placed on the top of the folding-machine or on the floorwithout disconnecting them from the folding-machine and the bridgeremain suspended from the press or detached and stored away Whereverdesired when not in use.

In the accompanying drawings, Figure 1 is a side view showing mycompletev invention connected with a folding-machine and the table of aprinting-press as required for practical use. Fig. 2 is an enlargedsectional detail view th rough the line 00 x of Fig. 1, clearly showingthe end of one of the bridge-boards resting in the supports providedtherefor in the bracket fixed to the frame of the foldingmachine. Fig. 3is a plan View showing the relative positions of the brackets fixed tothe folding-machine and the brackets and rollers and tapes detachablyconnected with the top end portion of the movable bridge.

A represents the frame of a paper-folding machine, and B the table of aprinting-press. A metal bracket 0, adapted to support the Serial No.385,943. (No model.)

rollers Nos. 1, 2, 3, and 4, fixed to the top corners of the frame A toaid in operating endless tapes in a common way. The upper branches thatextend rearward horizontally to support the roller No.2 and the bridge.These flanges are in right-angled position to each other, as clearlyshown in Fig. 2, and in connection with the flange d produce a recess orrest adapted to admit the lower ends of the side pieces of the bridge tosupport thebridge at various angles, as may be required in conmeetingthe folder with different presses at different times or at variabledistances from the same press.

11 represents a skeleton bridge composed of a series of straight planeboards is, that are rigidly connected by cleats m, fixed to their undersides. ropes fixed to the ends of the cleats are detachably andadjustably connected with the frame or table of a printing-press bymeans of buckles, snap-hooks, and screw-eyes, or in any suitable way, asrequired to thereby suspend the bridge and my complete sheet-carryingmechanism, as shown in Fig. 1.

C are metal brackets adapted to be detachably connected with the topportion of the bridge 11. Each has a bearing at its top end to support aroller No. 5 and a lateral branch at its lower end to support a rollerNo. 6 and a branch C adapting them to be rigidly connected with eachother by means of a rod 0 fixed thereto by means of setscrews or in anysuitable way. n are pulleybearers fixed to the rods C to support pulleysn and endless tapes or", that extend over the pulleys No. 1. of thebrackets 0 allow them to be placed on studs 1', fixed to the edges ofthe side pieces k of the bridge H, and horizontal open slots at theirtop portions admit them to engage screw-threaded projections r at theupper portions of the same pieces in such manner that they can beclamped fast to the edge by means of thumb-nuts r on the ends of thepins to securely and detachably fasten the brackets to the bridge asrequired to operate Leather stra s m cords or Open slots in the lowerend.

the tapes on the rollers for the purpose of carrying printed sheets fromthe deli very mechanism of a press to the folding mechanism of afolding-machine.

In applying my invention to a folding-machine and press I first suspendand adjust the bridge 11 from the press and then cut off the lower endof the bridge to make it the exact length required to engage the restsprovided therefor on the brackets 0, fixed to the folder-frame and thenattach the connected brackets C with the top of the bridge and place thetapes on the rollers in a common way.

It is obvious that my sheet-carrying device can be thus readily fittedand fixed in position as required for practical use, and also readilydetached and separated and placed away when not in use in such a mannerthat the tapes will remain on the rollers and the separated parts insuch position and condition that they can be speedily replaced andreadjusted whenever desired.

I claim as my invention 1. A sheet-carryingdevice comprising metalbrackets having branch roller-bearers and recesses for admitting andsupporting the corners of a bridge composed of wooden boards, saidbrackets being fixed to the corners of a folding frame, a bridgecomposed of a series of parallel boards in the same plane and rigidlyconnected by cross-cleats and provided with bracket-fastenings at theirupper end portions, and two metal brackets having branches androller-bearers and adapted to be detachably connected with the bridge,and means for adjustably and detachably connecting the said bridge witha printing-press to operate in the manner set forth, for the purposesstated.

2. A sheet-carrying device com prising metal brackets having branchroller-bearers and remit and engage the studs in the bridge, and

means for adjustably and detachably conneetin g the said bridge with aprinting-press to operate in the manner set forth, for the purposesstated.
